Abstract

PROCEDE DE PREPARATION DE LA 1,2-DIAMINOANTHRAQUINONE. LE PROCEDE CONSISTE A FAIRE REAGIR LA 1-NITRO-2-ACETYLAMINOANTHRAQUINONE AVEC L'HYDRAZINE OU L'HYDROXYLAMINE OU AVEC UN DERIVE D'HYDRAZINE OU D'HYDROXYLAMINE DANS UN SOLVANT PROTIQUE. APPLICATION DE LA 1,2-DIAMINOANTHRAQUINONE AINSI OBTENUE A LA PREPARATION DE COLORANTS DE CUVE, DE PIGMENTS ET DE COLORANTS DE DISPERSION.PROCESS FOR PREPARING 1,2-DIAMINOANTHRAQUINONE. THE PROCESS CONSISTS OF REACTING 1-NITRO-2-ACETYLAMINOANTHRAQUINONE WITH HYDRAZINE OR HYDROXYLAMINE OR WITH A DERIVATIVE OF HYDRAZINE OR HYDROXYLAMINE IN A PROTIC SOLVENT. APPLICATION OF 1,2-DIAMINOANTHRAQUINONE THUS OBTAINED IN THE PREPARATION OF TANK COLORANTS, PIGMENTS AND DISPERSION COLORANTS.
